To all whom it nut-y concern:

Be it known that I, ANDREW CHARLES LATI- MER, acitizen of the United States, residing at Meadow Lands, in the county of Washington and State of Pennsylvania, have invented certain new and useful Improvements in Mining- Cars; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification,

This invention relates to certain new and useful improvements in mining-cars, and has for its object the provision of a novel form of draw-bar which is to be used in connection with my improved miningcar, whereby a strong and durable construction will be obtained, which will withstand rough usage to which mine-cars are generally subjected.

Another object of this invention is to provide a novel form of brake, which can be readily constructed upon my improved minecar and easily and quickly manipulated to check or retard the movement of the car at any desired time.

Another object of this invention is a novel form of hook to be used on the bottom of my improved car and used where the car is elevated to the tipple by means of an endless chain, the said hook engaging with the hooks of the chain moving the car to its destination.

Still another object of my invention is a novel form of end-gate keeper, as hereinafter described.

Vith the above objects in view reference will be had to the accompanying drawings, wherein like numerals of reference designate corresponding parts throughout the several views of the drawings, in which Figure 1 is a side elevation of my improved car, the same being constructed and arranged in accordance with my invention. Fig. 2 is an inverted plan view of the same. Fig. 3 is an end view of the car, showing my improved end-gate latch. Fig. 4 is a detailed sectional view of the draw-head. Fig. 5 is a detailed perspective view of the hook used in connection with the car when the same is hauled by an endless chain or rope, and Fig. 6 is a detailed perspective view of a bracket or brace used in connection with the hook.

To put my invention into practice, I employ a hopper 1, which consists of the sides 2 and 3 and the bottom 4. The sides and bottom are secured by iron bands 5 and 5, and on one end of the car is hinged an end-gate 6, the detailed construction of which will be hereinafter described. A particular feature of my invention resides in the novel draw-bar as designated by the numeral 7. This drawbar is adapted to extend the entire length of the car and is placed beneath the floor 4 of the same, the construction of which is such that it braces the bands 5 5 of the car, also the axles of the same, which adds strength to the entire bottom of the car. This bar 7 is provided at each end with a head 8, a detailed view of which is shown at Fig. 4 of the drawings. These heads 8 bear against the edges of the bottom board of the car and are secured in position by bolts 9 and 15, the firstmentioned bolt 9 passing through the upper and lower flange of the head, the intermediate bottom board 4, the end bands 5, and the ends of the draw -bar 7 and the second bolt 15 through the bottom board 4, the lower flange of the head 8, and the draw-bar 7, thereby distributing the strain upon all of these several above-mentioned parts. These heads 8 are formed with pin-openings 10, by means of which one car may be coupled to another, and also with openings 28 to engage with the locking-pin 28 of the end-gate 6. The bar 7 is formed at the ends with bent portions to butt against the end bands 5 5 of the car and is also bent at the middle to pass over the square axles 11, bearing against and embracing the same, and is firmly and rigidly attached to the car-bottom by a suitable number of bolts 14. Intermediate of the axles 11 and between the draw-bar 7 and the bottom 4 of thecar is a metal bar 7, held in position by bolts 14, which serves to complete the attachment of said draw-bar to the car and distribute the strain of the same and its attached heads evenly to the car-bottom 4, the end bands 5 5, and from one axle 11 to the other, and the said drawbar and its intermediate bar 7 serving as a brace for the axles 11 against longitudinal movement.

The axles 11 of the car carry wheels 12, and these axles are secured to the bottom 4 by the brackets 13 at either side of the draw-bar and parallel thereto, the said brackets being firmly attached by means of bolts and are so formed to fit snugly about said axles and the center band 5.

Reference will now be had to Fig. 1 of the drawings, wherein the one side of my improved car is illustrated. On this side will be seen a brake which I prefer to use in connection with this car. A short bracket 16 will be noticed, forming a bearing for a rollerbar 16, Fig. 2, which extends transverse of the car and about one-half its width, to the outer end of which is attached a brake-block 17. This brake-block is in the form of a compound curve and is fitted with removable metallic shoes to engage with the wheels 12, said block being connected to a vertically-arranged lever 18, pivoted to a connecting-bar 19, the other end of which is joined to a hand-lever 21, fulcrumed at 22 to the side of the car 1 and confined within a strap 23, provided with a ratchet, by means of which the brake may be set and held at any desired position. It will be noticed that by this construction of brake I am able to apply the same to both wheels of the car, and by extending the rollerbar 16 to the other side of the car and fitting the same with another brake-block the entire set of wheels may be operated upon.

Reference will now be had to Fig. 3 of the drawings, wherein I have illustrated an end view of the car. The construction shown in this view is for locking the end-gate 6, which is hinged to the end-gate bar 25, said bar being supported by the car-band 5 and the hinges formed of metal straps 24, bent to embrace the woodwork and secured thereto by bolts. To the end of one of the hinges 24L is pivoted a latch-lever 26, which passes through a ratchet-bar 27, the said lever being connected to a pin 28 by a short chain, said pin adapted to engage with an opening 28, formed in the head 8, and lock the end-gate 6 from outward movement.

Where endless chains are in use for elevating the cars to the tipple or points of destination, I have constructed a hook, which will now be described. At Fig. 5 of the drawings I have shown the hook 29, which is substantially U-shaped and is adapted to be bolted to the under side of the center band 5, the apertures 33 being formed in the flanges for that purpose. Triangular-shaped brackets 30 (see Fig. 6) are providedand arranged at either side of the book 29 and securely riveted thereto, the said brackets being formed with flanges with bolt-openings 31 to connect the same to the bottom 4 of the car.

From the foregoing description, taken in connection with the accompanying drawings, it will be observed that I have constructed a very strong and durable car, which will be serviceable and readily manipulated.

I have illustrated the preferred manner of constructing my improved car, and it might be well to state here that I do not care to confine myself to this particular type of car upon which my improved construction may be used, as the same may be readily employed in connection with other types of cars.

It will be noted that various changes may be made in the details of construction without departing from the general scope and spirit of the invention. I

Having thus described my invention, what I claim, and desire to secure by Letters Patcut, is-
